DISHWASHING MACHINE Filed April 30, 1945 \NVENTOR I JOHN VAUDREUIL AT TCRNEYS Patented Apr. 20, 1948 UNITED STATES PATENTOFFICE 2,440,161 DISHWASHING MACHINE John Vaudreuil, Chicago, Ill. Application April 30, 1945, Serial No. 591,061

1 Claim.

1 My invention refers to dish washers, and has for its object to provide a multiple jet-spray of the planetary type, wherein the apparatus will thoroughly wash and rinse a batch of dishes, or the like, by directing a series of crlss-cross lets upon the dishes or other articles to be cleansed.

Another object of my invention is to provide a water supply pipe system for the machine wherein washing with a supply of soapy water, followed by rinsing with a supply of clear water, will result, due to the provision of a simple ball valve, which valve automatically separates the soapy water from the clear rinsing water, bearing in mind that both the rinsing water and cleansing water in the cycle of operation pass through a common pipe.

With the above and other minor objects in view. the invention consists in certain peculiarities of construction and combination of parts, as will be hereinafter fully set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings:

Figure 1 represents a perspective view of a dish washing machine, embodying the features of my invention, the same having parts broken away to more clearly illustrate structural features, and

Figure 2, an enlarged detailed sectional view of a ball valve for controlling and separating the rinsing water and soapy water.

Referring by characters to the drawings, A indicates a dome bowl for the reception of the articles to be washed, the same being of standard construction, and is supported upon a suitable legged stand B. Extending upwardly through the bottom of the bowl is a supply pipe C, the said pipe below the stand being in communication with a housing D, which housing carries a pump E, indicated in dotted lines, that is driven by a suitable motor F, all of which parts are standard construction and form no part of my present invention.

The dome also has communicating therewith v and near its bottom, a drain pipe G and, as indicated in dotted and full lines, a second drain pipe H communicates directly with the bowl bottom, and said drain pipe discharges into a supply pipe I, which pipe communicates with the motor housing D and pump E.

Mounted in the supply pipe I and fitted into the mouth of the drain pipe H is a valve cage I, which cage extends cross-wise of the supply pipe I.

As best shown in Figure 2 of the drawings, the cage is provided with a port 2, which port com municates directly with the valve cage I. The

bottom of the valve cage communicates with a clear water valve controlled supply pipe 3, and is provided with a valve seat 4, there being a similar valve seat 4' at the upper end of the case. which communicates directly with the drain pipe Hand a valve ball 5, normally resting by gravity upon the valve seat 4.

Pivotally mounted upon the end of the supply pipe C is a rotary master pipe arm 8, and each end of said master arm has rotatorily pivoted thereon, auxiliary tubes 1, 1', which tubes communicate directly with the main supply pipe C.

The tube I carries a jet-nipple 8 at one end and a balance weight 8' at the opposite end.

The tube 1', at its ends, carries hollow hubs 9 of a second pair of auxiliary tubes Ill, which tubes,

at their ends, are fitted with nozzles II, it bein understood that the tube 1 is thus over-balanced, with reference to the tube 1'.

Owing to the fact that the rotatory master pipe 6, at one end carries a distributing arm having a pair of auxiliary nozzles, this group of elements creates an over-balanced cluster of circular spray Jets. The above referred to cluster is counterbalanced by a single distributing arm 1 upon the other end of the master pipe and this distributing arm accomplishes the overbalanced results due to the fact that it has a spray nozzle on one end and a weight of predetermined size on the other end.

From the foregoing description it will be noted that a small quantity of rinsing water, under pump control, is discharged into the bottom of the bowl through the nozzles, up to the level of the drain pipe G. The supply from pipe 3 is cut off by the valve therein.

In this shallow body of water, a proper amount of cleansing powder of the soapy" type is introduced therein, it being understood that the top of the bowl now contains a batch of articles to be cleansed. Hence, the pump E, being started by the electric motor, will cause the soapy fluid to be sprayed upwardly in all directions by the group of rotatory nozzles, and said soapy water will form a continuous circuit by draining down through pipes H and I to the housing D, whereby it will be again discharged upwardly through the system of nozzles to thoroughly cleanse the dishes or other articles contained in the domed bowl, in repeated cycles.

After the articles are thoroughly cleansed in a rapid manner, due to the multiplicity of rotatory nozzles, the same are thoroughly rinsed by introducing clean hot water, under pressure, through the pipe 3, which water will displace the ball valve 3 I and cause the same to engaae. as indicated in dotted lines, the valve seat 4', whereby the soapy supply of water is cut oil and the clear water will be introduced to the series of rotatory Jets, tothus thoroughly rinse the previously washed dishes or other articles.

When the dish washer is to be emptied and cleaned after an operation. I provide a valve controlled drain pipe G for thoroughly draining of! all of the soapy water.

While I have shown and described a simple exempliflcation of my invention minutely as to detail, it is to be understood that I may vary the structural features within the scope of the claim.

I claim:

A dish washer comprising a rotatory master fluid discharge pipe, a two armed distributing tube mounted upon one end of the master pipe. a pair of auxiliary nozzled tubes revolvably mounted upon the ends of the distributing tube whereby go .4 whereby the master pipe is momentarily delayed in rotation to cause the series of overbalanced spray jets to the delayed and concentrated upon dishes to be washed.
